Class D Audio Amplifier - 160 Watts Stereo, 330 Watts bridged!
Brand New

Only 5 1/4" X 3 3/4" Clean & Thunderous Powerful Sound

Made in the USA by Class D audio

Overview

Our newest audio power amplifier is based on the Texas Instruments new TAS5615 digital amplifier chip. It's a high-performance, integrated stereo feedback, analog-input, digital amplifier with a power stage designed to drive 4-Ω to 8-Ω speakers at up to 160 W per channel in stereo, or up to 330W bridged. This amplifier requires only a 20V to 50V power supply to deliver high-quality, high-efficiency audio amplification.

This amplifier is configured with two BTL channels or one PBTL channel and the possibility to apply either a single-ended or a differential (ballanced) analog input signal.

The input section of the amplifier has two OPA1632 opamps...  very high-performance, fully differential, audio operational amplifier designed to operate with single-ended or differential input signals. Output section features our custom made high performance inductors and metallized polypropylen capacitors. This is a very high quality power amplifier, and as always, made with the state-of-the-art materials and impeccable workmanship Class D Audio is known for.

Lead Free & Energy Efficient

These amps are hand made by us, Class D Audio, right here in the USA. There are about 180 parts and components that make up this amplifier, most very small surface mount on the top and bottom layer of the board. We use the highest quality parts and components such as OXI-Cap low ESR tantalum capacitors, KOA resistors in the input path, metalized polypropylene capacitors and custom made ultra low distortion inductors are used on the input side, with a whole lot of very high quality components in between. The specs are actually  better then I list here, and I believe you will find this to be one of the best sounding amps you have ever heard... at any price!

Review from recent customer:

Tom,

      A finally got time to get my class d amp together today and it sounds great, I can't believe the sound it has. I have built several amplifiers and been arround amps and have several that I have collected through the years. All kinds ,solid state , tube , all classes, repaired all kinds and I have not heard any that sound any better than this thing. It's so clean and detailed it will steal the pants off lots of expensive high end equipment. So clean it brought the flaws out in my preamp.
